The 19 most expensive buildings ever constructed

Casino resorts make up the majority of the most expensive buildings ever made, adjusted for inflation.

Hotels and resorts also feature in the top 19, while two residential towers make an appearance - one of which is used by just a single family.

There are just two office skyscrapers in the ranking, suggesting that more specialised developments require more money.

Most were built this century, but a few were opened in the late 80s and early 90s, with their inflation adjusted price soaring accordingly.
